When ZGC is enabled, we skip oop verification in OopMapSet::all_do().
There's no good reason to skip that. The comment suggesting this is
skipped because a safepoint can happen between a load and the barrier is
incorrect. We can still do the verification as is_in_or_null() doesn't
require the address to have a "good" color.
Also, once JDK-8224675 is integrated, this comment will make even less
sense.
